The main site for The Association of Graveyard Rabbits hasn’t been kept updated but I found Canadian members. Not all active but at least the lights are still on (or the sites are still loading). I’d be glad to list more Canadian members if one comes along.
The Graveyard Rabbit of British Columbia, Canada – M. Diane Rogers
Rock of Ages: Grave Concerns (The Graveyard Rabbit of Alberta)
My Grave Addiction (Ontario)
Graveyard Rabbit of Grey County, Ontario – Janet Iles
